Hermann Raphael Rodensteen, born around 1525 in Vollenhove, was a distinguished Dutch organ builder who worked across Europe, from Scandinavia to Austria, before settling in Zwickau in 1559. His career began under the influence of his father, Raphael I. Rodensteen, also an organ builder, and alongside his brothers who followed in the family craft. Despite the mystery surrounding his initial training, it is suggested he might have apprenticed under a master in Utrecht. By 1550, Rodensteen was commissioned to build an organ in Roskilde Cathedral, Denmark, a project completed by 1555, marking his first significant international work. His reputation was such that he was described as an "honest and modest man" during his time in Denmark.

Rodensteen’s move to Zwickau became permanent when he married Clara Hofmann in 1559 and established his workshop. His works during this period indicate his prominence in the field; his organs were known for their rich Renaissance style, often pedalless and starting not at C but likely at F on the keyboard. Notable works include the organs for Roskilde Cathedral, the Copenhagen Castle Church, and several in Saxony. His contributions to the design and construction of organs, which featured elaborate casework and potentially innovative stop combinations, underscore his significant role in the evolution of organ building in Europe. His last recorded works date to before a debilitating illness in 1576, and he passed away in 1583, leaving a legacy of craftsmanship and innovation.
